provided with arcuate portions 21 midway of their lengths having acurvature such as to grip the cupped projection 24 between them. Thus,said strips 2s clamp the cupped proiection 14 of the thermostat inposition, and they may then be suitably attached thereto, as bysoldering. so as to fixedly secure the thermostat against displacement.In place of embracing the cupped projection on said end wall the stripsII could be formed to embrace any other suihbie pro- Jection on thethermostat.

Said opposed strips II arebent in wardly as shown invFig. 2, and provided with arcuate portions 30 midway of their lengths ofsubstantially the curvature of the-stem il so as Thereby the thermostatis fixedly secured in the tubular wall I and the valve stem i1 isprovided with a guide which assures that said stem shall moverectilinearly with respect to the axis of said wall by merely providingsaw cuts in said tubular wall and bending inwardly the strips'so formed.j

Valve member Iii may be provided with a leakage aperture ll so that whenthe valve member is on its seat a small but predetermined circulation ofwater will occur to prevent the water around the thermostat beingstagnant. The thermostat is preferably charged at a pressure belowatmospheric so that at normal temperatures the valve is held against itsseat by atmosphericpressure acting on the movable .end'wall of saidthermostat, but if the thermostat leaks and be-' comes inoperative sothat the internal pressure becomes equalized with the external pressure,the expansibleand collapsible wall 28 will expand under its ownresiliency, or the action of a spring if preferred, to lift the'valvemember ill on of its seat and maintain a circulation through the tubularcasing I to prevent overheating.

It will therefore be perceived that by the present invention atemperature regulator has been provided which is very simple inconstruction and which may be manufactured inexpensively because all ofthe fabricating operations are simple in character. The casing ll may becut from a continuous tube or drawn as a cup and the bottom removedtherefrom. In the latter event, either the annulus I! or the valve diskIt or both may be cut from. the disk so removed from the bottom of thecup to reduce the amount wall a. said wall is provided with a pair ofcuts 28 soas to provide a pair of oppositely disposedstrips 2| .tions oflimits thereof.
